Croats Released Gillian Sharpe reports from The Hague that the United Nations war crimes tribunal today freed three indicted suspects. The prosecutor said there is not enough evidence to try them. The three were among 10 Bosnian Croats who turned themselves in last October. They had pleaded innocent to taking part in an ethnic purge of Muslims in Central Bosnia in 1993. It is the first time the War Crimes Tribunal has released suspects.
